             Summary: ConcurrentModificationException in JobLeaderIdService
                 Key: FLINK-7201
                 URL: https://issues.apache.org/jira/browse/FLINK-7201

          Issue Type: Bug
            Reporter: Xu Pingyong
            Assignee: Xu Pingyong


 java.util.ConcurrentModificationException: null
 	at java.util.HashMap$HashIterator.nextEntry(HashMap.java:922)

Because the jobLeaderIdService stops before the rpcService when shutdowning the resourceManager´╝î
jobLeaderIdService has a risk of thread-unsafe.
